Acoustic egg sponges are the most common acoustic material used to provide volume acoustics. Acoustic egg sponge is included in almost every project specification. It is especially used as a wall and ceiling finishing material in mechanical areas. These sponges, which we call fireproof, are only black in color. If colored acoustic egg sponges are desired, the surface of low-density viol sponges can be coated by selecting the desired color from the flock colors. Their effects on sound insulation differ according to their thickness and density. If sound insulation is intended, it should definitely be used with a barrier.
If sound insulation is to be provided by using acoustic sponges, high density sponges should be preferred and should be used with barriers. For example; If an acoustic sponge with a 70dns 63mm barrier is preferred, the efficiency will increase.
